Comprise 40 megahertzes, the control device that has 386 computing machines (CTC P1) of (RTD) analog input of decimal system sensing tape and digital output board is configured to receive and store the data from sorter, and transmits and select injection signal to each Electromagnetic Control pump.
In operation, JAMESWAY 84 platforms that contain 84 eggs are installed on the INOVOJECT travelling belt.Each platform is by sorter, and each egg is by between photo-emission source and the photodetector.Data are sent to controller, use the predetermined level that blocks, and identify each egg and are suitable for injection (viable) or are unsuitable for injection (infertile, empty or omit).Controller generates and transmits selects injection signal to give each syringe pump.Each egg is pierced through by INOVOJECT injection tool, yet those syringe pumps that have only and be placed on the pin in the viable egg to interrelate are provided vaccines.This system is per hour about can inject 45,000 eggs.
Above be that explanation is of the present invention, and can not take it as restriction.The present invention is determined by following claim, comprises the equivalent of claim here.
